First, add to find the number of male and female students.
216 + 207 + 198 + 194 = 815 males
193 + 214 + 197 + 201 = 805 females
Second, add to find the total number of students
815 + 805 = 1620
Third, find the number of students in ninth and tenth grade.
216 + 207 + 193 + 214 = 830
Fourth, put into a fraction.
830/1620
Fifth, simplify the fraction.
830/1620 → 83/162
Therefore, the answer is C.
Best of Luck!
To solve this problem and calculate the area of the sphere, you must apply the following formulas:
Formula N° 1:
V=4/3(πr³)
V is the volume of the sphere (V=3,000π m³).
r is the radius.
Formula N° 2:
A=4πr²
A is the area of the sphere.
r is the radius.
As you can see, you don't have the value of the radius "r". So, you must rewrite the Formula N° 1, and clear "r":
V=4/3(πr³)
(3,000)(3)=4πr²
r³=9,000/4π
r=(9,000/4π)<span>^1/3
</span> r=13.1037 m
Then, to calculate the area of the sphere, you must substitute the value of "r" into the Formula N° 2:
A=4πr²
A=4π(13.1037)²
A=2,158 m²
<span>What is the surface area of the sphere to the nearest square meter?

The answer is: 2,158 m²
You can write an equivalent expression with this knowledge by taking a two numbers, and multiplying both of them by a number. You can extract the number by taking the gcf of both of them, and dividing them both by it and putting the numbers in a parenthesis and multiplying the numbers by the gcf.<span />
4(a+b+c+d) is the only possible answer:)
Answer:
Compound interest is calculated by;
Initial amount x (100%xinterest%)^(years)
My workings which I also checked with another and they agree doesn't come back to your options. But closest answer is B.
Step-by-step explanation:
$450x(1.048^4) = $542.82
$750x(1.0375^4) = $868.99
$542.82 + $868.99 = $1,411.81
